BACKGROUND ART

[0004] Chemokine is known as a basic protein having endogeneous leukocyte chemotactic and activating abilities and strong heparin-binding abilities. At present, it is considered that chemokine is related to not only the control of infiltration of specific leukocyte at the time of inflammations and immune responses but also the development and homing of lymphocyte under physiological conditions and migration of hemocyte precursor cells and somatic cells.

[0005] Differentiation, proliferation and cell death of hemocytes are controlled by various types of cytokine. In the living body, inflammations are found topically and differentiation, maturation and the like of lymphocytes are carried out at certain specified sites. That is, various necessary cells migrate into certain specified sites and accumulate therein to cause a series of inflammations and immune responses. Accordingly, migration of cells is also an indispensable phenomenon in addition to differentiation, proliferation and death of cells.

[0006] Migration of hemocytes in the living body starts firstly in the development stage by the shift of hematopoiesis started in the AGM region into permanent hematopoiesis in bone marrow via fetal liver. Furthermore, precursor cells of T cells and thymus dendritic cells migrate from the fetal liver into the bone marrow and then into the thymus gland and cytodifferentiate under thymus environment. The T cell which received clone selection migrates into secondary lymphoid tissues and takes part in an immune response in the periphery. The Langerhans' cell of the skin activated and differentiated by capturing an antigen migrates into the T cell region of a topical lymph node and activates naive T cell therein as a dendritic cell. The memory T cell performs its homing again into the lymph node via lymphatic and blood vessels. Also, B cell, T cell in the intestinal epithelium, γδ T cell, NKT cell and dendritic cell migrate from bone marrow without passing through the thymus gland and differentiate to take part in an immune response.

[0007] Chemokine is deeply related to the migration of these various cells. For example, MIP3β, SLC and its receptor CCR7 play an important role in the migration and homing of naive T cell, memory T cell and the mature dendritic cell which captured an antigen into a topical lymphoid tissue for the dendritic cells to encounter efficiently with the T cells. The T cell and dendritic cell necessary for controlling antigen-specific immune responses are hardly observed in the secondary lymph node of a PLT mouse having deficiency in the expression of SLC (J. Exp. Med., 189(3), 451 (1999)).

[0008] MDC, TARC and its receptor CCR4 play an important role in the migration of Th2 cell into topical sites in immune and inflammatory responses in which the Th2 cell is related. In a rat fluminant hepatitis model (P. acnes+LPS), an anti-TARC antibody suppressed increase of the amount of ALT in blood and increase of the expressing amounts of TNFα and FasL in the liver and also improved lethality of the rats (J. Clin. Invest., 102, 1933 (1998)). Also, an anti-MDC antibody decreased the number of eosinophils accumulated in the lung interstitium and suppressed airway hypersensitivity in a mouse OVA-induced airway hypersensitivity model (J. Immunology, 163, 403 (1999)).

[0009] MCP-1 and its receptor CCR2 are related to the infiltration of macrophage into inflammation sites. An anti-MCP-1 antibody showed an effect to suppress infiltration of monocyte and macrophage into glomerulus in a rat anti-Thy1.1 antibody glomerular nephritis model (Kidney Int., 51, 770 (1997)).

[0010] Thus, chemokine receptors are greatly related to the control of inflammation and immune responses through a mechanism in which they are expressed at certain specified periods in variously specific cells and the effector cells are accumulated in a region where chemokine is produced.

[0011] Acquired immunodeficiency syndrome (called AIDS) which is induced by human immunodeficiency virus (hereinafter referred to as “HIV”) is one of the diseases of which their therapeutic methods are most earnestly desired in recent years. Once infection with HIV is completed in a CD4-positive cell which is a principal target cell, HIV repeats its proliferation in the body of the patient and, sooner or later, completely destroys T cell which takes charge of the immunological function. During this process, the immunological function is gradually reduced to cause fever, diarrhea, lymph node enlargement and the like various immunodeficiency conditions which are apt to cause complications with pneumocystis carinii pneumonia and the like various opportunistic infections. Such conditions are the onset of AIDS, and it is well known that they induce and worsen Kaposi sarcoma and the like malignant tumors.

[0012] As the recent preventive and therapeutic methods for AIDS, attempts have been made to, e.g., (1) inhibit growth of HIV by the administration of a reverse transcriptase inhibitor or a protease inhibitor and (2) prevent or alleviate opportunistic infections by the administration of a drug having immunopotentiation activity.

[0013] Helper T cells which take charge of the central of immune system are mainly infected with HIV. It is known since 1985 that HIV uses the membrane protein CD4 expressing on the membrane of T cells in the infection (Cell, 52, 631 (1985)). The CD4 molecule is composed of 433 amino acid residues, and its expression can be found in macrophages, some B cells, vascular endothelial cells, Langerhans' cells in skin tissues, dendritic cells in lymphoid tissues, glia cells of the central nervous system and the like, in addition to the mature helper T cells. However, since it has been revealed that the infection with HIV is not completed by the CD4 molecule alone, a possibility has been suggested on the presence of factors other than the CD4 molecule, which are related to the infection of cells with HIV.

[0014] In 1996, a cell membrane protein called Fusin was identified as a factor other than the CD4 molecule, which is related to the HIV infection (Science, 272, 872 (1996)). It was confirmed that this Fusin molecule is a receptor (namely, CXCR4) of stromal derived factor-1 (hereinafter referred to as “SDF-1”). In addition, it was confirmed also in vitro that the SDF-1 specifically inhibits infection of T cell tropic (X4) HIV (Nature, 382, 829 (1996), Nature, 382, 833 (1996)). That is, it is considered that the HIV infection was inhibited by the binding of SDF-1 to CXCR4 preceding HIV, thereby depriving HIV of a foothold for infecting cells.

[0015] Also at that time, it was discovered that another chemokine receptor CCR5, which is a receptor of RANTES, MIP-1α and MIP-1β, is also used at the time of the infection with a macrophage tropic (R5) HIV (Science, 272, 1955 (1996)).

[0016] Accordingly, substances which can compete with CXCR4 and CCR5 for HIV, or which can bind to HIV virus thus causing the virus unable to bind to CXCR4 and CCR5, could become HIV infection inhibitors. Also, there is a case in which a low molecular compound initially discovered as an HIV infection inhibitor was actually a CXCR4 antagonist (Nature Medicine, 4, 72 (1998)).

[0017] Based on the above, it is considered that the chemokine/chemokine receptors are deeply related to the inflammation, immune disease or HIV infection. For example, it is considered that they are related to the inhibition of various inflammatory diseases, asthma, atopic dermatitis, nettle rash, allergic diseases (allergic bronchopulmonary aspergillosis, allergic eosinophilic gastroenteritis and the like), glomerular nephritis, nephropathy, hepatitis, arthritis, chronic rheumatoid arthritis, psoriasis, rhinitis, conjunctivitis and ischemia-reperfusion injury, in the treatment of multiple sclerosis, ulcerative colitis, acute respiratory distress syndrome, shock accompanied by bacterial infection, diabetes mellitus and autoimmune diseases, and transplant rejection, immunosuppression, metastasis prevention and acquired immunodeficiency syndrome.

[0418] (1) The method via an acyl halide may be carried out, for example, by reacting carboxylic acid with an acyl halide (e.g. oxalyl chloride or thionyl chloride etc.) in an organic solvent (e.g. chloroform, methylene chloride, diethyl ether or tetrahydrofuran) or without a solvent at −20° C. to reflux temperature. And then the obtained acyl halide derivative may be reacted with amine in an inert organic solvent (e.g. chloroform, methylene chloride, diethyl ether or tetrahydrofuran), in the presence of a tertiary amine (e.g. pyridine, triethyl amine, dimethyl aniline or dimethylaminopyridine) at 0-40° C. As an alternative, the obtained acyl halide derivative may be reacted with amine in an organic solvent (e.g. dioxane or tetrahydrofuran) using an alkaline aqueous solution (e.g. sodium bicarbonate or sodium hydroxide) at 0-40° C.

And then the obtained mixed acid anhydride derivative may be reacted with amine in an organic solvent (e.g. chloroform, methylene chloride, diethyl ether or tetrahydrofuran), at 0-40° C.

[0420] (3) The method using a condensing agent may be carried out, for example, by reacting carboxylic acid with amine in an organic solvent (e.g. chloroform, methylene chloride, dimethylformamide, diethyl ether or tetrahydrofuran) or without a solvent, in the presence or absence of a tertiary amine (e.g. pyridine, triethylamine, dimethylaniline or dimethylaminopyridine), using a condensing agent (e.g. 1,3-dicyclohexyl carbodiimide (DCC), 1-ethyl-3-[3-(dimethylamino)propyl]carbodiimide (EDC), 1,1′-carbodiimidazole (CDI), 2-chloro-1-methylpyridinium iodide or 1-propanephosphonic acid cyclic anhydride), in the presence or absence of 1-hydroxybenzotiazole (HOBt), at 0-40° C.

[0421] The reaction described in (1), (2) and (3) may be carried out under an inert gas (e.g. argon or nitrogen) to avoid water in order to obtain a preferable result.

[0422] Moreover, the amidation may be carried out with the compound in which R³ or R⁴ is hydroxyl group.

[0426] (wherein R^(1-1A-4), R^(2-1A-4), R^(3-1A-4), R^(4-1A-4) and R^(5-1A-4) have the same meanings as R¹⁻¹, R²⁻¹, R³⁻¹, R⁴⁻¹ and R⁵⁻¹ respectively, and wherein at least one group represents a group containing carboxyl, hydroxy, amino or thiol, and the other symbols have the same meanings as defined hereinbefore).

[0430] A protecting group of thiol includes, for example, benzyl, methoxybenzyl, acetoamidomethyl, triphenylmethyl or acetyl.

[0431] The protecting group of carboxyl, hydroxy, amino or thiol includes the above one, and in addition to the other protecting group which is removable selectively and easily, for example, one described in T. W. Greene et. al., Protective Groups in Organic Synthesis, Third Edition, Wiley-Interscience, New York, 1999.

[0432] The removal of a protecting group of amino may be carried out by the method described hereinbefore.

[0447] (wherein R¹⁻², R²⁻², R³⁻², R⁴⁻² and R⁵⁻² have the same meanings as R¹, R², R³, R⁴ and R⁵ respectively, and wherein at least one nitrogen represents quaternary ammonium salt, and wherein Q is halogen) may be prepared by reacting the compound of the formula (XI)

R⁰-Q  (XI)

[0448] (wherein R^(o) is C1-4 alkyl or C1-4 alkyl substituted by phenyl, and Q is halogen.).

[0449] The reaction is well known, and it may be carried out, for example, in an organic solvent (acetone, dimethylsulfoxide or methyl ethyl ketone etc.) at 040° C.

[0450] Among the compounds of the formula (I), the compound, in which at least one nitrogen represents N-oxide, i.e., the compound of the formula (I-3)

[0457] [Pharmacological Activities]

[0458] Efficacy of the compounds of the invention of the formula (I) was confirmed, e.g., by the following tests.

[0459] As described in the foregoing, in order to carry out screening of a compound capable of inhibiting binding of HIV to CXCR4 or CCR5 which is a receptor on the CD4-positive cell, it is a more directive method to carry out it in an assay system that uses HIV virus. However, the use of a large amount of HIV virus in the screening is not practical due to a difficulty in handling it. On the other hand, since both the macrophage tropic (R5) HIV-1 and the ligands, that is, RANTES, MIP-1α and MIP-1β, bind to CCR5, it can be presumed that certain common characteristics are present in the CCR5 binding sites of the HIV side and the RANTES, MIP-1α and MIP-1β sides, and in the binding sides of CCR5 to the ligands, that is, RANTES, MIP-1α and MIP-1β, and HIV Accordingly, in order to find a compound capable of inhibiting adsorption of HIV virus to cells, which has an inhibitory mechanism different from the current anti-AIDS drugs (reverse transcriptase inhibitors and protease inhibitors), it is possible to use an assay system that uses an endogeneous CCR5 ligand, RANTES, MIP-1α or MIP-1β instead of HIV.

[0460] Concretely, e.g., since CCR5 is a G protein-coupled seven transmembrane type receptor, an assay system in which the effect of RANTES on the transient increase of Ca ion induced via CCR5 can be carried out for screening a compound capable of inhibiting binding of RANTES to CCR5. Since both of the T cell tropic (X4) HIV and SDF-1 bind to CXCR4, similar idea can be considered for screening a compound.

[0461] [Test Methods]

[0462] (1) Isolation of Human CCR5 Gene Human placental cDNA was prepared using Marathon cDNA amplification kit (Clontech). PCR primers hCCR5Xbal-F1: 5′-AGCTAGTCTAGATCCGTTCCCCTACMGAAACTCTCC-3′ (SEQ ID NO:1) and hCCR5Xbal—R1: 5′-AGCTAGTCTAGAGTGCACMCTCTGACTGGGTCACCA-3′ (SEQ ID NO:2) were designed based on the sequence of GenBank U54994.

[0463] Using the human placental cDNA as the template and using Ex Taq (Takara), PCR reaction (2 minutes at 95° C.→(30 seconds at 95° C., 45 seconds at 60° C., 1 minute at 72° C.)×35 times) was carried out. The thus amplified PCR product was subjected to a 1% agarose gel electrophoresis, purified using QIAquick Gel Extraction Kit (QUIAGEN) and then digested with a restriction enzyme Xbal. The digested fragments were ligated to an expression vector pEF-BOS-bsr using DNA Ligation Kit Ver. 2 (Takara) and transformed into Escherichia coli DH5a. By preparing the resulting plasmid pEF-BOS-bsr/hCCR5, its DNA sequence was verified.

[0464] (2) Culturing of CHO Cell

[0465] CHO-dhfr(−) was cultured using Ham's F-12 (containing fetal bovine serum (10%), penicillin (50 U/ml) and streptomycin (50 mg/ml)). Also, the transduced cell was cultured by adding blasticidin (5 mg/ml) to the above medium.

[0466] (3) Transduction into CHO Cell

[0467] The plasmid pEF-BOS-bsr/hCCR5 was transduced into the CHO-dhfr(−) cell using DMRIE-C reagent (Gibco BRL). After 48 hours, the medium was replaced with a medium containing 5 mg/ml of blasticidin to carry out the selection, thereby establishing a stably over-expressing cell.

[0468] (4) Inhibition Test on the Binding of RANTES to CCR5 (Activity of RANTES to Induce Transient Increase of Ca Ion).

[0469] The thus established human CCR5 stably over-expressing CHO cell (CCR5/CHO cell) was suspended in Ham's F-12 medium containing FBS (10%) and dispensed in 3.0×10⁶ cells/well portions into a 96 well plate. One day after culturing at 37° C., the culture supernatant was discarded, and Ham's F-12 medium (containing Fura-2AM (5 μM), Probenecid (2.5 mM) and HEPES (20 mM; pH 7.4)) was dispensed in 80 μl/well portions to carry out 1 hour of incubation at 37° C. under shaded condition. After washing twice with 1× Hanks/HEPES (20 mM; pH 7.4) solution, the same solution was dispensed in 100 μl/well portions. Each of the test compounds was added to the thus Fura2AM-incorporated CCR5/CHO cell, and 3 minutes thereafter, a recombinant human RANTES (PeproTach) diluted with 1× Hanks/HEPES (20 mM; pH 7.4) solution was added thereto to a final concentration of 10 nM. Transient increase in the intracellular Ca²⁺ concentration induced by the human RANTES was measured using a Ca²⁺ detector for 96 well use (Hamamatsu Photonics), and inhibition ratio (%) of the test compound was calculated by the following calculation formula.

Inhibition ratio=(Ec−Ea)/Ec×100

[0470] Ec: measured value of Ca²⁺ transient increase by RANTES

[0471] Ea: measured value of Ca²⁺ transient increase by RANTES when a test compound was added.

[0472] As a result, the compounds of the invention showed an inhibition ratio of 50% or more at 10 μM. For example, the compound of Example 2 showed an IC₅₀ value of 0.027 μM, and the compound of Example 3 an IC₅₀ value of 0.37 μM.

[0473] An assay system for finding a compound having adsorption inhibition effect on CCR5 directional HIV strain was described in the foregoing, and it is possible as a matter of course to find a compound capable of inhibiting the activity of CCR5 or a ligand thereof using this system. In the same manner, it is possible to find a compound capable of inhibiting the activity of other chemokine receptor or a ligand thereof. For example, a system for finding a compound capable of inhibiting the activity of CCR2 or a ligand thereof can be constructed. Since CCR2 is a G protein-coupled seven transmembrane type receptor similar to the case of CCR5, it can be carried out by measuring the effect of a ligand of CCR2, e.g., MCP-1 on the transient increase of Ca ion induced via CCR2.

[0474] (5) Inhibition Test on the Binding of MCP-1 to CCR2 (Activity of MCP-1 to Induce Transient Increase of Ca Ion).

[0475] A human CCR2-expressing cell, e.g., a human monocyte cell strain THP-1 (ATCC No. TIB-202), was suspended in RPMI 1640 medium containing FBS (10%), Fura-2AM (5 μM), Probenecid (2.5 mM) and HEPES (20 mM, pH 7.4) to a density of 5.0×10⁶ cells/ml and incubated at 37° C. for 30 minutes under shaded condition. This was mixed with 4 to 8 volumes of 1× Hanks/HEPES (20 mM, pH 7.4)/Probenecid (2.5 mM) and further incubated at 37° C. for 30 minutes under shaded condition. After washing with 1× Hanks/HEPES (20 mM, pH 7.4)/Probenecid (2.5 mM) solution, the thus washed cells were resuspended in the same solution to a density of 2.0×10⁶ cells/ml and dispensed in 100 μl/well portions into a 96 well plate. Each of the test compound solutions was added thereto, and 3 minutes thereafter, a recombinant human MCP-1 (PeproTach) diluted with 1× Hanks/HEPES (20 mM, pH 7.4)/Probenecid (2.5 mM) was added thereto to a final concentration of 30 nM. Transient increase in the intracellular Ca²⁺ concentration induced by the human MCP-1 was measured using a Ca²⁺ detector for 96 well use (Hamamatsu Photonics), and inhibition ratio (%) of the test compound was calculated by the following calculation formula.

Inhibition ratio=(Ec−Ea)/Ec×100

[0476] Ec: measured value of Ca²⁺ transient increase by MCP-1

[0477] Ea: measured value of Ca²⁺ transient increase by MCP-1 when a test compound was added.

[0478] [Toxicity]

[0479] The toxicity of the compounds of the present invention is very low and therefore the compounds may be considered safe for pharmaceutical use.
